Enolizable ketones have been reacted in a one‐pot method with aromatic aldehydes, acetyl chloride and acetonitrile at room temperature in the presence of SnCl4/SiO2 to furnish the corresponding β‐acet‐amidoketones in improved yields. Acetylation of an aromatic hydroxyl group was observed while using 4‐hydroxybenzaldehyde or vanillin and the corresponding β‐acetamidoketones were isolated in an excellent
                                    在室温下,存在SnCl 4 / SiO 2的情况下,可烯化的酮与芳族醛,
乙酰氯和
乙腈以单锅法进行反应,从而以提高的产率提供相应的β-乙酰胺基酮。当使用
4-羟基
苯甲醛或
香兰素时,可以观察到芳香族羟基的乙酰化,并且分离出相应的β-乙酰
氨基酮的产率很高。
